How negation is expressed by means of manual and/or non-manual markers has been described in a wide range of sign languages. This work has suggested a split between sign languages requiring a manual negative element in negative clauses (manual dominant sign languages) and those where a non-manual marker only can be used (non-manual dominant sign languages) (Zeshan 2006; 2004).

However, Oomen and Pfau (2017) have recently indicated that such a typological split is too radical. They show that larger data sets are necessary to identify the range of expressions used within one sign language to expr...
